Fair test

Title - Gummy worms
Purpose: What do you want to learn/find out?
To find out what will happen if we put water and calcium chloride with sodium alginate?

Hypothesis: Try to predict the answer to the problem. Another term for hypothesis is ‘educated guess’. This is usually stated like ” If I…(do something) then…(this will occur)
The water and the calcium chloride produced the best because they both go together to make the mixture of water and calcium chloride.

Materials: List everything you will need to conduct your experiment.
Calcium chloride, Sodium alginate, polymer and pipettes.

Experiment procedure: The fun part! Design a test or procedure to confirm or disprove your hypothesis. Write down each step so that someone else could do the same experiment.
1. We mixed water with calcium chloride.
2. Then we got the pipettes and filled it with sodium alginate.
3. Fill the water and add the sodium alginate.
4. Then we watched the sodium alginate move around the cup of water.
5. When we finished watching it we took it out of the cup
6. Then we tipped out the water and all of us were holding the sodium alginate.

Analysis/Data: Record what happened during the experiment.
When we finished the little drops of sodium chloride were floating in the cup of water and calcium chloride.

The water didn’t go with sodium alginate.

When we took out the sodium alginate it was yuck, green and soggy.

When we added all the sodium alginate together the cup of water turned into to green.

Conclusion:Review the data and check to see if your hypothesis was correct.
The calcium chloride does go with water.
